Bach Standard Series Trumpet Mouthpiece in Silver 1-1/2B

Bach Classic Series Mouthpiece Vincent Bach was a rare combination of artist and engineer. He constantly changed his mouthpieces in search of the perfect design. It wasn't until the mid 1960's that he stopped and finally settled on more standardized design. It was around this time that the formalization of the 27 throat and backbore to cup letter (A=24, B=7, C= 10, etc.) created a standard for mouthpiece making that is still used today. These standards are now known as the Classic Series.

Bach trumpet mouthpieces have been designed in an orderly progression from the largest to the smallest diameters, and from the deepest to the most shallow cup, all with a choice of rim designs Rim shape is described for each individual model Model numbers progress numerically from model no 1 with the largest cup diameter, to model no 20C with the smallest cup diameter Cup depths are notated with letters
